📦 array-utils-mini

A lightweight JavaScript utility library that re-implements core and intermediate array methods from scratch — perfect for learning, interviews, and low-level control. No built-in array methods used (except length)!

🚀 Installation

npm install array-utils-mini

📚 What’s Inside?

✅ Basic Methods

• push(arr, value)
• pop(arr)
• shift(arr)
• unshift(arr, value)
• indexOf(arr, value)
• includes(arr, value)
• reverse(arr)

🯩 Medium-Level Operations

• map(arr, callback)
• filter(arr, callback)
• reduce(arr, callback, initial)
• slice(arr, start, end)
• splice(arr, index, deleteCount, ...items)

✨ Bonus Features

• unique(arr) — remove duplicate values
• max(arr) — get the maximum value
• min(arr) — get the minimum value
• insertArrayAt(arr, pos, toInsert) — insert an array in a specific position of an array

🔧 Usage

import * from 'array-utils-mini';

const arr = [1, 2, 2, 3, 4];

console.log(unique(arr)); // [1, 2, 3, 4]
console.log(max(arr));    // 4
console.log(min(arr));    // 1

push(arr, 5);
console.log(arr);         // [1, 2, 2, 3, 4, 5]

🧠 Why Use This?

• Great for learning how array methods work under the hood.
• Helpful for DSA practice and JavaScript interviews.
• Lightweight and zero dependencies.
• Easy to contribute new methods or enhancements.
